networking - can some one explain communication between two clients in below network? -

-

pc1 -> switch -> switch b -> pc2.

ip address of pc1 -192.168.2.1 ip address of pc2 -192.168.2.2

if ping pc2 pc1, how packet forwarded?

what packets source ip address, destination ip address, source mac address , destination mac address @ port connecting pc1 , @ port connecting pc2 ?

you can omit switches between hosts, because don't affect or modify communication between hosts. store informations mac address reachable @ interface reduce spamming network segments useless data. whole communication done in few steps:

  1. pc1 want send icmp packet pc2, don't know mac address yet
  2. network:: pc1: arp - address of 192.168.2.2?
  3. network:: pc2: arp - address of 192.168.2.2 aa:bb:cc:dd:ee:ff
  4. pc1 has l2 address, can send packet
  5. network:: pc1: icmp echo-request - src-mac: 11:22:33:44:55:66, src-ip: 192.168.2.1 ... dest-mac: aa:bb:cc:dd:ee:ff, dest-ip: 192.168.2.2
  6. pc2 recieves icmp echo-request, , want send echo-reply, don't know l2 address of 192.168.2.1
  7. network: pc2: arp - address of 192.168.2.1?
  8. network: pc1: arp - address of 192.168.2.1 11:22:33:44:55:66
  9. network: pc2: icmp echo-reply - src-mac: aa:bb:cc:dd:ee:ff, src-ip: 192.168.2.2 ... dest-mac: 11:22:33:44:55:66, dest-ip: 192.168.2.1

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
